Claims. (Cl. 251-240) The present invention relates to a faucet. Morepar ticularly, the invention relates to a faucet construction of thetype adapted for use on containers of liquids for human consumption, andthe embodiments of this invention relate to improvements over myco-pending application, Serial No. 233,509, iiled June 2l, 1951, forFaucet now U.S. Patent 2,764,3 85 granted September 25, 1956.

One of the primary problems to be overcome in a design of faucets foruse on containers of liquids for human consumption such as a coffee urn,tea dispenser, and the like is that of sanitation. In faucets intendedfor this purpose, it is absolutely necessary that the faucetconstruction lend` itself to being cleaned with little diiculty 'becauseof the fact that personnel generally charged with cleaning such faucetsare not inclined 1 to thoroughly Wash or cleanse inaccessible orhaId-to-clean parts.' -Consequently, it is essential that the faucetconstruction be easily assembled and disassembled for cleaning and notinclude any hard-to-clean portions such as a threaded surface which'isexposed to the lliquid inthe container and wherein accumulation of filth`and lbacteria might occur. It is also desirable to provide a faucetconstruction which may be readily manipulated by a handle with ato-andfro movement and` yet which can be readily disassembled to permitthe valve construction of the faucet to be readily taken apart andcleaned.

It is therefore an object of the present invention to provide a faucetfor use on containers of liquids for human consumption which can vbeeasily and quickly disassembled for cleaning and sterilizing.

Another object of the invention is to provide a novel faucetconstruction for use on containers for liquids that is adapted to` beeasily and thoroughly cleaned with a minimum of effort, and which doesnot have anyrelatively inaccessible hard-to-clean portions exposed tothe liquid in the container on which the faucet is used.

.A` further object of the invention is to provide a novel faucetconstruction which is relatively simple and inexpensive to manufacture..

Another object of the invention is to provide a faucet constructionwhich has a readily movable valve construction, -a pivoted handleconstruction for manipulating the valve, and which may be readily'detached from the faucet construction.

A feature of the invention is the provision of a faucet constructionwherein friction-fitted parts are utilized to hold the faucet inassembled relation to a detachable connection on the container.

Another feature of the invention is the provision of a novel faucetconstruction wherein resilient O-ring gaskets are utilized to hold thevarious parts of the faucet in assembled relation. Y

Still another feature of the invention is the provision' of a novelhandle construction for biasing the valve construction from closed toopen position in which the han- `die construction is detachably mountedwith a bayonet Patented .timev 14, 1960 HCC 2 constructioncomplementally formed with respect to the faucet housing for pivotalmovement of the handle.

Another feature of the invention is the provision of a handleconstruction wherein the handle is detachably mounted with a bayonetconstruction wherein the handle moves angularly about one, of the pinsof the bayonet construction.

Another feature of the invention is the provision of a handleconstruction wherein the handle is detachably mounted with a bayonetconstruction and the handle moves in a plane about an axis at rightangles tothe plane of the handle. y

Another feature of the invention is a faucet construction which has avertical discharge spout in which the valve construction is detachablymounted and in which the handle for manipulating the valve is mounted atthe upper end with a bayonet construction, and is provided with auniversal mounting wherein the valve may be opened in any one of fourpositions of the handle with the handle moving from front to rear, orfrom left to right from its normal Vertical position.

Still another feature of the invention is a faucet construction formedwith a vertical discharge spout in which is mounted the detachable valveconstruction with the valve handle operatively mounted at the upper endof the discharge spout with a bayonet construction, and wherein thevalve may be opened by a rearward movement of the handle.

Another feature of the invention is the provision of a faucetconstruction wherein the valve construction is operatively mounted inthe horizontal passage of the faucet construction leading to the spoutwherein the handle is detachably mounted from the valve body by abayonet construction, and the valve is opened by a forward movement ofthe handle from its vertical position... n

Another feature of the invention is the provision of a faucetconstruction in which the valve therefor is mounted in the horizontaltubular body of the valve construction, and in which the valve is openedby a forward angular movement of the valve handle from its verticalposition about the horizontal axis of the bayonet con.- struction fordetach-ably mounting the handle from the valve body.

Referring to Figs. l through 4 of the drawings, more direction of thearrows, illusparticularly a sanitary faucet 1li constructed inaccordance With the present invention is illustrated. The faucet 10 ismounted on a container for liquids .such as a coffee urn 11 or the like,a part thereof being shown, to which a tubularV member 12 is supportedin an aperture 13 in one side wall 11. The tubular member 12 has ahanged end portion 14 positioned within the container 11 and an innerpassageway 15 communicating with the interior of thecontainer 11.Disposed between the flanged end 14 and the side wall of the container11 is a iiexible annular gasket ring 15, and disposed` between theoutside surface of the wall of the container 11 and a nut 17 isa secondannular gasket ring 1S which, if desired, may have a hardened surface 19or may be in the form of a separate metal washer. The nut 17 serves toretain the tubularmember 12 in place on the container 11, and upondrawing the nut 17 up tightly the anged end 14 is `drawn up firmlyagainst the inner gasket ring 16. The inner gasket ring 16 and theoute-r gasket ring 1S then serveto `sealably enclose the portion of theouter threaded surface 2i) of the tubular member -12 complementallyformed to threadably receive the nutl 17 and prevent liquid fromcontacting the threaded surface. By this construction, the tubularmember 12 can be readily secured 23 lie in the same plane. The endportion of the tubular member 12 is complementally formed to thepassageway 26 and is adapted to be press iitted within this passage- Way26, the press lit being preferably accomplished by means ofga pluralityof spaced .O-ring gaskets 27 axially on the free end of the tubularmember '12, and seated in a plurality of longitudinally' spacedcircumferential groves 2S formed aroundthe outer surface of the tubularmember 12. By reason of the press t provided for the tubular member 12within the inner passageway 26 of the faucet body 21, the `faucet body21 can be readily attached to or detached `from the container 11,thereby allowing the body member and valve assembly to be easily removedfor cleaning and, similarly, the tubular member 12 may be readilyremoved for cleaning by detaching in the reverse order to which it isassembled. Because of the novel manner in which the tubular member 12 isfrictionally supported within the inner passageway 26 of the body member21, no threaded or other hard-to-clean surfaces are exposed to theaction of the liquid within the container, thereby assuring that thefaucet will be thoroughly cleaned after disassembly.

Cooperating with the free end of the hollow tubular portion or valvedpassageway 23 of the combined spout and valve assembly 24 is a movablelvalve member 30. The movable valve member 3i) comprises a cylindricallyshaped disk 31 having an annular groove 32' formed around the peripherythereofsand a removable O-ring 33 seated in the groove; The O-ring 3 3is adapted to engage a tapered or conical surface 34 in the end of thecylindrical downspout Z4 and cooperate therewith in adiskvalve fashion.The movable vvalve member 30 thus comprised is connected by means of aconnecting link or stem 35 to a valve .operating means 3,6. Thevalveuoperating means comprises a .valve stem head Vportionor plunger 37secured -tojthe end of the valve stern `1r5..oppos,ite the movablevvalve member 39, and slidably seated in the passagewayZS in the combineddownspout and valve assembly Zifwith the outerend portion thereofoutwardly v accessible by an operator-operated or handle ,means 138 tobe more particularly described later. Inthis embodiment of theinvention, the plunger 37 is secured to the valve stem 35 by means of atransverse groove. 439 comto the container 11 without in any mannerexposing the threaded surface thereon to the liquid within thecontainer, thereby preventing thev accumulation of rot and lth of thethreaded surface which. is extremely hard to clean and, for that reason,quite often neglected. This Y construction has been fully disclosed andclaimed in my aforementioned co-pending application, Serial No. 233,-

5.09, l.now U.S. Patent 2,764,385 granted Septemberk 25..

plementally formed to a spherical or ball-like end 40 turned from theinner end of the valve stem 35 asfshown in Fig. 1. The groove 39 extendsdiametrically across the head portion 37. Cooperating Withthe plunger 37is a compression spring 42fhaving one of-.the ends vthereof engaging theplunger 37 contiguous tothe axis thereof at the point of connection .ofa spherical end y40 to the transversegroove .39, and uthe otherend-thereof engaging a substantially annular sealing gasket 43 seated onan annular shoulder 44 formed by the intersection of a greater diameterpassageway 23 with a lesser diameter portion passageway 23. It is `alsowithin tl1e`scope of the mvention that the compression spring 42 mayengage a rigid disk (not shown) which, in turn,`abuts the sealing gasket43 as described with reference to the sealing gasket construction zofthe yaforementioned Ico-pending application; By this construction, thercompression spring 42 serves to normally' biasfthe'- plunger 37outwardly, which action results in firmly seating the movablevalvemember 30 on the valve seat formed by the tapered edge 34 of the hollowtubular member 24.

The movable valve mcmberm 34;*` is preferably constructed in such amanner-that the outer diameter of the cylindrically shaped disk 31 isless than the crosssectional-dimensions of the inner passageway 23 ofthe downspout 24' and the inner passageway 23sogthat by removing .theO-ring 33,' the cylindrically-shaped disk 31 can be withdrawn throughthe inner passageways 23 and 23', thereby allowing the -faucet assemblythus comprised to be readily disassembled for cleaning. Having removedthe Icylindideally-shaped-disk 31'and-the stem 36 from the upper end ofthe `combined downspout and valve assembly 24, the component parts canthen be readily disassembled by detaching the plunger 37 of the valveoperating means 36 by transversely moving the plunger and spherical end40 with respect to each other, thus detaching the spherical end 40 fromthe groove 39. After the plunger 37 isdetached from the valve stem 35,the spring 42 and gasket 43 may also be detached. The cleaning of theseparts requires little or no concentration since each of these partspresent a relatively smooth surface tothe individual or person in chargeof cleaning the parts. Thus, it is seen that the faucet construction isparticularly adapted for use on containers of liquid for humanconsumption wherein the maintenance of sanitaryconditions requires .afaucet construction that may be thoroughly cleaned with a minimum ofeffort and attention. This valve construction is that as similarlydescribed with reference to my co-pending application, Serial No.406,491, tiled January 27, 1954 for thermostatically Controlled CombinedTea and Coffee Maker, now abandoned.

If the faucet is to be used on a container of cool liquids, theconstruction heretofore described and illustrated in Fig. l will suicethough it is necessary to have an addi- Itionally long plunger 37 toextend outwardly beyond the upper end of the tubular member 24, asillustrated and described with reference to the first-mentionedco-pending application. However, if the faucet is to be used on acontainer of hot liquids or evenwith a container of cool liquids, it issometimes more desirable to use an additional operator-operated lever orhandle means 38 as illustrated, and which in the normal unopenedposition as illustrated in Fig. l stands in axial alignment orsubstantially vertical according to the inclination of the down- A spout24 as in the form ofthe embodimentin Figs. 1 and 2. It is also preferredto have a handle means which may open the movable valve member 3i) asshown in either of the dotted positions A and B of Fig. 1, wherein thevalve member 30 may be opened upon angular movement toward the containeras shown in position A, or in an angular movement away from thecontainer as shown in position B; and similarly, the valve means 30 maybe opened if the handle means 38 is moved ang-ularly to the left asshown in the dotted position C, or angularly to the line as shown in thedotted position D, Fig. 2.

Referring more particularly to Figs. l, 2, 3, and 4, the improved handleconstruction for detachably connecting the handle to the upper end ofthe combined downspout and valve member 24 is arranged to operativelyconnect the handle means^38 to the plunger 37 for actuating the valvemeans for` opening and closing the valve member 30 by asymmetricallyformed bayonet construction 45 and 46 on the front and rearfaces at `the upper end of the tubular member 24, the connecting axisthereof either parallel or substantially parallel to the longitudinalaxis of the members 12 and 21, and these axes transverse to thelongitudinal axis of the valve stem 35 and all the axes lying in thesame plane. The axis of the diametrically arranged front and rear-pivotpins 47 and 48 is positioned at right angles to the longitudinal axis ofthe handle means 38 and the longitudinal axis of the valve stem 35..

The handle 38 comprises an insulated handle 'gripping portion 49integrally aixed to a metal stem portion 50 having integrally formedtherewith a disk-like member 51 to which the pivot pins 47 and 48 arediametrically i mounted in complementally formed holes 52, Fig. 1. Thethickness of the disk 51 is slightly thicker than the diameter of thepins so that as the pins are pressed in forming a forced t, there willnot be any deformation of the disk. It is also within the scope of the4invention that the holes 52 may be drilled diametrically, and a singlepin instead of separate pins inserted to form the protrudin'g'end asillustrated. The ends of the pivot pins 47 and y48 extend slightlybeyond the outer diameter or" the tubular member 24. The bayonetconnections 45 and 46 preferably comprise the pins 47 and 48 on thedisk-like member 51 of the handle, and the symmetricallyl formed slots53 fand 54 are positioned at opposite ends of a diameter of the combineddownspout and valve assembly 24 in alignment with the axis of thetubular member 12 and body member 21. Each of the slots 53 and 54,respectively,A comprises an axially extending slot 55 and 56 whichpermits angular movement of the handle to the respective dotted positionA andjB as shown in Fig. l, wherein in the position A, the pin 47 is inthe upper end of the slot 55 and the pin 48 is movable downwardly in theslot 56, suicient clearance being had to give maximum angular movement.'In the position B, the pivot pin 48 is in the upper end of the slot 56and the pin -47 is moved toward the bottom of the slot 55. In thishandle movement from the normal axial position of the handle to eitherposition A or B,

the edge of the disk-like member 51, for example, contiguous to the pin48 serves as a cam and actuates the plunger 37 against the bias of thespring 42, opening the valve 30 to the dotted position 30', Fig. 1, uponmovement of the handle 38 to the position A. Similarly, the edge of thedisk-like member 51 contiguous to the pin 47 biases the valve member 30to its open position against the action of the spring l42 by themovement of the handle 38 to the position B.

In order to detach the handle 38 from the combined downspout and valve'assembly 24, the handle 38 is moved axially downwardly until the pins 47andv 48 are in alignmentas shown in the dotted position 47', Fig. l, ofthe opening 57, Figs. 1 and 2, of each of the curved slots 58 and 59,the slots 58 and 59 extending upwardly, providing diametrically oppositeopenings 61 and 62 in the upper peripheral edge of the tubular member24, Figs. 2 and 3. With the pins 47 and 48 `in the. dotted position 47',Fig. 2, by a counterclockwise movement, referring to Fig. 2, an upwardand outward movement of the pins 47 and 48 through the curved slots 58and 59 permits the handle to be detached, the pins 47 and 48 beingremoved through the openings 61 and 62. Upon removal of the handle, thebias of the spring 42 forces the plunger 37 to its outermost positionwith the movable valve member 30 in the closed position. Also, in thisposition, the spring 42 biases the sealing gasket 43 against its annularseat 44.

In order to replace the handle, the diametrically positioned pins 47 and48 are inserted in the openings 61 and 62 and axial pressure is applieddownwardly, and as the handle is pushed downwardly it is slightlyrotated in a clockwise direction so that the pins pass through theopening 57 into their axially extending slots 55 and 56 taking thedotted position 4'7. handle, the spring 42 biases the pins 47 and 48into their upward position at the upper end of the slots 55 and 56 asillustrated in Figs. 1, 2, and 3. The faucet is then in a position to beoperated by movement either forward or backward as in the positions Aand B, or

.sideways to the positions C and D to open the valve.

In the detachment of the valve and its respective parts from the tubularmember 24, the handle is moved downwardly axially, forcing the valve tothe dotted position 30, Fig. l, to permit removal of the O-ring 33. Thehandle is then detached as previously described, and the bias of thespring forces the upper end of the tubular member-24 so that it may begrasped by the finger tips and the entire valve assembly removed,whereupon the plunger 37, spring 42, and sealing gasket 43 may bedetached from the valve stem for cleaning and sterilizing. Aftercleaning and sterilizing the valve body including the part 21 and thepart 24, the valve parts are assembled in the reverse order and replacedthroughrthe upper end of the tubular member 2'4. The handleis replacedas Upon release of thev described, and upon forcing the handle axiallydownwardly until the end of the valve member appears below the bottomend, the O-ring 33' may be replaced.' After the 'O-ring has beenreplaced, the handle is released and the entire valve is ready to bereassembled after the cleaning of the tubular member 21 which also hasbeen det-ached from the container 11 as described. rl`he body member 21is forced with an axial and rotary motion over the O-rings 27 of thetubularrnember4 12, whereupon the faucet is assembled in position on thecontainer.

Referring to Figs. and 6, there is illustrated another embodiment of myinvention wherein a modified faucet somewhat similar to that of theprevious embodiment of Fig. 1 is assembled to the container by a flangedunion coupling 65, and the operating handle 66 is so mounted that thevalve is only opened by a movement of the handle corresponding to theposition B of Fig. l. Since like reference characters will indicate thesame or similar parts, only the changes in the particular parts will bedescribed. The tubular member 12 is modified over the construction ofFig. 1 by a conically-shaped end 67 which may be separately formed asillustrated or integrally formed as a part of the tubular member 12. Thelargest diameter of the conically shaped member 67 of the tubular member12' must be formed to clear the standard opening 13 of Vthe container 11so that it may be placed in position in the container preferably fromthe interior of the container, and the flexible annular gasket rings 16and 18 may be assembled in position together with the metal washer 19and nut 17. If the annular member 67 is separately formed, it may bebrazed in position. The tubular body member 21 corresponding to themember 21 vof Fig. l is formed with a conical opening 68 complementallyformed to receive the conically shaped end 67, and is also threaded asat 69 to receive the complementally formed locking nut 7i?. The lockingnut 70 has an annular flanged portion 71 engaging an annular shoulder 72of the conically-shaped end 67 to detachably assemble the body member 21of the faucet to the tubular member 12 which is detachably connected tothe container 11. With this construction, the connection of the tubularmember 12' is normally permanent, though with suitable modificationwithin the skill of one `in the art, the parts may be detachablyassembled; for example, the connection of the member 67 to the tubularmember 12' may be threaded along the complementally formed connection73, if desired, rather than aflixed by braz-ing for ease of assemblingor disassembling.

The combined downspout and valve assembly 24 is substantially the sameas that described with reference to Fig. l with the exception, however,that the connection of the handle 66 to the upper end of the tubularmember 24' is modied' slightly. The operating handle 66 is formed withan insulated hand-gripping member 49 and stem 50 but with a modifieddisk-like member 51 differing from the disk-like member 51 of Fig. l inthat a segment of the disk-like member 51 is removed to the cord 74,Fig. 6. The pins 47 and 43 are rotated 90 fromthe position of the pinsof Fig. 3, and are eccentrically mounted in the eccentrically positionedhole 52 drilled parallel to an axis through the stem Si?, both axesbeing at right angles to the longitudinal axis of the body member 21',Fig. 6. In this construction the symmetrical bayonet slot constructions45' and 46 need not be provided with as long axially extending slots 74'and 75 corresponding tothe slots 5S and 56 of the embodiment of Fig. l.Openings 61' and 62', Fig. 6, are provided for the detachment of the-handles 66 as has been described with reference to the embodiment ofFig. 1, the only diiference in the operation being that Whereas thehandle was removed from' Vthe slots 55 and 56 with a downward,counterclockwise, and outward movement, the handle 66 of Fig. 2 isremoved by a downward, clockwise and outward movement in view of theeccentric positioning of the pins as illustrated in` Fig. 6 from thediametrical positioning of the pins as shown in Fig. 3. The handle 66 ofthe embodiment of Fig. 5 is attached in the reverse order. As thedetachment of the valve mechanism of the faucet of Fig. 5 is similar tothat of the embodiment of Fig. 1 after the O-ring has been removed,further description of this operation is unnecessary.

Referring to Figs. 7 through 12 and Figs. 13 through 16, there will bedisclosed two additional embodiments of my invention wherein improvedfaucet constructions are had usinga bayonet connection which permitsdetachment of the handle and the valve mechanism of the faucet, and alsowherein the pins of the bayonet connection serve as a pivot in theembodiment of Figs. 7 through 12 and pivots in the embodiment of Figs.13 through 16. Referring to Figs. 7 through 12, the embodiment in whichthe handle 80A is pivoted about one of the pins 81. may be moved from aninclined vertical position t'o the dotted position E, Fig. 7. In thedotted position of Fig. 7 the handle is shown pivoted about the lowerpin 81 within the symmetrical bayonet constructions 45 and 46'comparable to the -bayonet construction of the embodiment of the faucetconstruction of Figs. 1 and 2. In the embodiment of Fig. 1, theaxiallyextending slots S5 and 56 are mounted in the vertical tubularmember or combined cylindrical downspout and valve means 24, whereas inthe embodiment of Fig. 7, the handle means 80 is operatively connectedto the faucet body member 32 which operatively mounts the valve meanssimilar to the valve means of the embodiment of Fig. 1; but in theembodiment of Fig'. 1, the fluid dispensed is discharged through theopen end of the combined downspout and valve member 24, and in theembodiment of Fig. 7, the movable valve member 30 opens within thecontainer 11 as illustrated in the dotted construction 30y of Fig. 13.Each of these embodiments of Figs. 7 and 13 is an improvement over theembodiment disclosed and claimed in my copending application, Serial No.233,509, nled June 26, 1951 for Faucet, now U.S. Patent 2,764,385granted September 28, 1956. In each of these embodiments of Figs. 7 and13, the tubular valve members S2 and 82' extend through a bore 83 in adownspout 84. Each of these downspouts of the embodiments of Figs. 7 and13 is provided with an axially extending slot 85, Figs. 7, 9, and 10 ofthe embodiment of Figs. 7, 13, and 14 of the embodiment of Fig. 13. Thisslot prevents the dripping of the liquid after the valve has been shutoff and serves the same function as the movable valve member 30 in theembodiment of Fig. 1, which as it seals against the tapered opening 34prevents dripping of the Huid from the end of the spout.

In each of the embodiments of the faucet constructions 10a and 10b ofFigs. 7 and 13, the tubular members S2 and 82' are detachably connectedto a tubular member 12a as shown in Fig. 13 for detachably connectingthe faucet to the contianer 11. The construction of the tubular member12a and associated parts is substantially the same as that disclosed inmy co-pendiug application, Serial No. 233,509, filed June 26, 1951., nowU.S. Patent 2,764,385 granted September 25, 1956, and differs only fromthe embodiment of Fig. 1 in that in the embodiment of Fig. 1, thetubular member 12 is interiorly mounted in the bodyrmember 21,- whereasin the embodiments of Figs. 7 and 13, the tubular members 82 and 82 areslidably mounted within the tubular member 12a. In the embodiment ofFigs. 7 and 13, the tubular member 12a is similarly formed with aflanged end portion 14', and is provided with a threaded surface 20 tocomplementally frictio'hally retain either the faucets 10a or 10b totheir respective tubular' contions 12'acomplementa1ly formed yto each ofthe faucets and aixed to their respective containers 11' to permit the`detachment of each of the faucet constructions and each of theconnections 12a for proper cleaning and sterilizing. Since thedetachment of the modified connection 12a is similar to the connection12 of Fig. 1, further description is unnecessary. Likewise, as each ofthe valve mechanisms of the embodiments of Figs. 7 and 13 issubstantially identical to the construction described with reference toFig. l, further description of the valve parts including the movablevalve member 30, its O-ring 33, valve stem 35', compression spring 42,and plunger 37 is-unnecessary and therefore like or similar referencecharacters denote the same parts.

Each of the handle means 80 is similar in construction to the handlemeans of Figs. l and 6 with the exception that the insulated handlegripping member 49' is aixed to a substantially U-shaped stem 86which-permits the handle means 80 to be inclined forwardly -toward thecontainer 11 so that the movement is automatic on the part of theoperator to open the valve of the faucet by pushing the handle forwardrather than to pull it backwards. The forward end of the stem isaixed'to or integrally formed with a disk-like member 87 which issimilar to the disk-like member 511 of the embodiment of Fig. 1. Thedisk-like member S7 is formed at right angles to the forward end of theaxis of the stem 86, and the angular shape of the stem 86 upon themounting of the disk-like member S7 at right angles to the longitudinalaxis of the faucet body member 82 inclines the handle S forwardly. Thepins 81 are mounted on the axis of the disk in the same plane as theaxis of the U-shaped stem and handle so that the handle is verticallymounted and in the same plane as the axis of the handle and thelongitudinal axis of the valve stem 3S as the pins are mounted in theaxially extending slots 55 and 56, Figs. 7, 8, 9, and 10. As the slotconstruction of the bayonet joint is similar to that of the embodimentof Fig. 1, like reference characters will indicate the same or similarparts. Removal of the handle means- 80 of the embodiment of Fig. 7 issubstantially the same as that of the handle means 38 in that theVhandle is forced inwardly so that the pins take the dotted position 81'as shown in Figs. 8 and 10, whereupon with a counterclockwise movementlooking in the direction of Fig. 9, the handles are rotated and movedoutwardly through the curved slots 58 and 59 and are then detachedthrough the openings 61 and 62 in the end of the faucet body member 82.The handle is returned in the reverse order. In order to detach thevalve means 30, the O-ring 33 is removed upon the disk 87 being movedaxially inwardly so that the valve means extends beyond the inner end ofthe faucet body member 82 to the dotted position of Fig. 7, after whichthe handle is detached as described above, and the valve parts may bewithdrawn for cleaning and sterilizing as described with reference tothe embodiment of Fig. 1. In opening `the valve, the handle is moved tothe dotted position E as shown with the lower pin 81 serving as thepivot point for the angular movement of the handle so that the upperedge of the disk-like member 87 cams against the upper surface of theplunger 37 opening the valve means against the bias of the spring. Uponreleasing the handle, the valve is closed.

Although in the embodiment shown in Figs. 7 through l2, it is desirableto open the faucet by an inward movement of the handle, the constructionof the bayonet joint also permits the opening of the Valve upon outwardmovement of the handle in which case the handle pivots about the upperpin 81 in the upper slot S6. It is also within the scope of theinvention that the depth of the lower slot S6 may be locatedcorresponding to the dotted position Si', Fig. l0, of the pin in whichcase the bottom edge of the slot S would be at the bottom edge of theopening 57. In this position, an outward pull might slightly open thevalve but not suicient to permit the discharge of theiiuidsatisfactorily from the container'. B'y modifying the shape of thebottom slot 55, it is possible to so shape the slot that there would besubstantially no opening of the valve in the outward movement of thehandle though permitting the detachment of the handle through thebayonet connection.

The pins 31, Figs. 11 and 12, may be press fit in complementally formedopenings 52., Fig. 12, which extend partially within the disk-likemember S7, or the pin 81 may extend through an opening drilledcompletely across the diameter of the disk-like member.

Referring to the embodiment of Figs. 13 through 16, the faucetconstruction is substantially identical to that described with referenceto Figs. 7 through 12 with the exception that in the embodiment of Fig.13, the handle is pivoted about the axes of the pins 81 rather thanabout the upper or lower pin 81, depending on the direction in which thehandle is moved for the embodiment of Fig. 7. The handle construction ofFig. 13 with respect to the location of the pins I81 is somewhat similarto the embodiment of Fig. 5, wherein the pins 47 and 43 are mountedeccentrically with respect to a diameter of the disk-like member 51. Amodified bayonet slot construction 90 is had, and the bayonet slotconstruction is symmetrically arranged on a cord of the tubular member82 so that upon a slight angular rotation-in a counterclockwisedirection as Viewed in Fig. 14, the pins 81" may be detached through theopenings 61 and 62.' corresponding to the similar openings 61 and 62 asviewed in Fig. 9. `The axially extending slots 91 and 92, Figs. 13 and14, are formed with a point 93 to locate the pins 81" in the outerportion 94 of each of the slots 91 and 92. Upon angular movement of thehandle to the dotted position F, Fig. 13, the handle is rotated on thepins 81", journaled'within the outer slotted portion 94 so that theupper edge of the disk 87 engages the plunger 37, moving the plungerinwardly against the bias of the spring 42 so that the valve means 30opens to the dotted position of Fig. 13, permitting iiuid to flow fromthe downspout 84 of the faucet. Upon release of the handle, the springbiases the valve means to its closed position, shutting off the iiow offluid, and the slotted opening 85 permits air to enter the downspout 84,pre venting drip of the fluid when the valve is in its closed position.

Referring to Figs. 15 and 16, the pins 81" are assembled eccentric to adiameter of the disk 87' which is perpendicular to a plane through thelongitudinal axis of the handle 80. openings 52 as described withreference to the embodiment of Figs. 1l and 12, and similarly, ifdesired, a pin or pins 81" may extend through a drilled hole extendingacross a cord of the disk. In this embodiment, the location of thebayonet connection is similar to the location of the bayonet connectionfor the handle in the embodiment described with reference to Figs. 5 and6. In this embodiment of Fig. 13, it is unnecessary to remove a portionof the disk as described with reference to Fig. 6 to permit actuation ofthe handle. The handle of this embodiment is removed in the same manneras described with reference to the embodiment of Fig. 7 and, similarly,the parts of the valve mechanismv are. removed in the same manner forcleaning and sterilizing. The valve means and the handle are replaced inthe reverse order.

From the foregoing description, it can be appreciated that there havebeen disclosed several embodiments of the invention which provide afaucet for use on containers of liquids for human consumption, which isadapted to be easily and quickly assembled for cleaning andsterilizing.v The faucet has no relatively inaccessible or hard-to-cleansurfaces which are exposed to the action of the liquid so that'k afterdisassembly the parts thereof can be readily cleaned without requiringconcentrated attention. v Further, the various embodiments are rela- Thepins 81" may be mounted in l1 tively simple in design and adapted 'to bemanufactured inexpensively.

It is also evident that there has been disclosed a simple bayonetconstruction for detachably mounting a handle for a faucet constructionon a valve body thereof, which operatively mounts the handle foractuating the valve means of the faucet and yet permits readydisassembly ofthe handle and assembly thereof for detachably mountingthe valve parts of the valve means of the faucet for cleaning,sterilizing, and servicing. 'It is also obvious that there have beendisclosed severalarrangements for pivotally mounting a handle, utilizingthe bayonet construction of this invention either about one pin of the'bayonet construction or about an axis 'of the pins of the bayonetconstruction. f

Furthermore, there has been disclosed a handle construction wherein thehandle may be operated in any one of several directions, `either in ato-and-fro movement from the center location of the handle toward andaway from the container, or in a to-and-fro` movement to the left orright of the faucet. Also, there have been disclosed other arrangementsof the handle construction wherein the valve of the faucet may be openedprimarily either with a to-and-fro movement from a central position orsolely by a movement in one direction.

There have also been disclosed several embodiments of the faucetconstruction 'in which the valve jmeans is directly operated in thedownspout or in which the valve means is operated in a passage leadingto adownspout, and in each of the several embodiments disclosed therehas been disclosed a simple construction for attaching and detaching thecoupling means for the faucet to the container for cleaning andsterilizing, and, similarly, there has been disclosed a simplefrictional joint construction for the disassembly ofthe faucet tothecoupling means as well as a conventional type of coupling using athreaded joint.

There have also been disclosed simple detachable handle constructionsincorporating a bayonet construction for quickly attaching and detachingthe handles to the valve bodies and for actuating the valve mechanism.

Having thus described my invention, it is obvious that variousimmaterial modifications 'may be made in the same without departing fromthe spirit of my invention; hence, I do not wish to be understood aslimiting 'myself to the exact form, construction, arrangement andcombination of parts herein shown and described, o'r uses mentioned. l
